Records of NJ Birds: Featherbed Lane
Fall 2000
Hannah Bonsey Suthers

The succinct summary of this breeding season is early and wet, migrants and their chicks being about two weeks early, and August being the wettest on record. Trails and areas with sparse ground cover eroded. Forbs were lush and shrubs showed a good fruit set. Hickories and oaks were dropping their mast by end-August.

The first fledglings of Neotropical migratory birds in our weekly mist nets were a Worm-eating Warbler and a Blue-winged Warbler on June 12, followed by an early Catbird on June 19. Fledglings were sparse until the third week in July, implying early nesting failures due to inclement weather, for the second year in succession. Catbirds managed a second wave of fledglings on 24 July, and a third wave on 19 August. Fall fledglings, Canada Warbler and Northern Waterthrush, were banded on 19 August.

A new Veery age record beat the national age record previously set by one of our birds. This male Veery banded on 25 May 2003 as an after-second-year bird was recaptured on 31 May 2009, and again on 26 June 2011 at the age of after-ten-years and two months. Our previous national age record was set by a female Veery banded on 3 July 1980 as an after-hatch-year, and recaptured on 2 July 1989 at age after-ten-years.

The singing male census indicated 62 nesting species, 23 being Neotropical migrant species representing 37% of all species. (Compare with the high of nearly 47% in 1985.) Total breeding male individuals were up this year to 608, 41% being Neotropical migrant species.

Constant effort mist-netting and banding for the Monitoring Avian Productivity and Survivorship program resulted in 180 new birds of 28 species. (2008 had 341new birds of 43 species.) Returns of birds banded in previous years were at 15%, or 32 birds of the 212 individuals captured.

As cooperators with the University of California LA Center for Tropical Research and The Conservation Genetics Resource Center, we pulled two tail feathers from each of 71 birds. The DNA in skin cells attached to the quill is used to determine the population origin of an individual bird, and stable isotope analysis of a portion of the feather is used to determine the latitude where the feather was grown. Researchers are trying to determine migratory connectivity, that is, the wintering grounds for specific populations of breeding birds and vice versa. The conservation implications are tremendous.
